Newbee is correct. I am the distributor/importer (and in charge of repairs) for all Opera Audio and Consonance high-end audio components in the North American (USA and Canada).
As I have said, they are one of the largest and most respected Chinese manufacturers in the field. I don't want to single them out, as my opinion from "comparing notes" with other industry insiders is that my experience is not out of the ordinary. But, to put a positive spin on things that deserve it, the sonics of their CD players at their respective pricepoints are class leading, and their tube equipment is not only solidly built and reliable, but especially good sounding.
